OBJECTIVE: To explore the effect of E-Flow imaging on the radiotherapy of cervical lymph nodes metastasized from nasopharyngeal carcinoma. METHODS: A total of 52 nasopharyngeal carcinoma patients with 94 invasion neck lymph nodes were treated with conventional radiotherapy. Lymph node size, hemodynamic parameters, and blood supply were detected by E-Flow imaging and two-dimensional ultrasound before and after the radiotherapy. The relationship between those examinations and radiotherapy effect was analyzed. RESULTS: Of the 94 metastatic cervical lymph nodes from nasopharyngeal carcinoma before the radiotherapy, 40 disappeared, 52 reduced, and 2 maintained the original size after the radiotherapy. Blood flow in all residual lymph nodes decreased or disappeared. Artery flow spectrum in the lymph node was changed from the high-speed high impedance to low-speed low resistance. The size of cervical lymph node and blood flow before the radiotherapy were associated with clinical efficacy (P < 0.05). CONCLUSION: E-Flow imaging plays an important role in assessing the efficacy of radiation therapy by changing the blood supply of cervical lymph node and its size before and after the radiotherapy. |
